A surgical fastener and method for attachment of a soft tissue graft to a bone tunnel is disclosed. The surgical fastener comprises a screw and collar. The screw having a conical head and blunt threads. The collar having a conical shape so as to fit over the conical screw head and containing side wall openings. Secure fixation of a soft tissue graft within a bone tunnel may then be achieve by passing the end(s) of the graft through the side wall openings in the collar and then holding tension on the graft while the screw is driven through the collar into the bone tunnel. With seating of the screw head in the collar the soft tissue graft is be firmly held in place as the screw threads and collar compress the graft into the side walls of the tunnel and the graft tails are captured securely by the interface of the screw head and collar. This surgical fastener offers multiple sites of secure graft fixation to avoid slippage of the graft during healing and lies within the bone tunnel so as to avoid being prominent. |
